Abstract
A surface treated high aspect ratio talc may be surface treated with a surface treatment agent including a polymeric species including one or more ether linkages. Functional compositions including a surface treated high aspect ratio talc may be polymer compositions. A process for preparing a surface treated high aspect ratio talc may include mixing the high aspect ratio talc and surface treatment agent. A process for preparing a polymer composition may include combining a high aspect ratio talc with a polymer in an amount of at least about 30% by weight, based on the total weight of the polymer composition.
